You can find your subject academic advisor here. They can answer any of your academic related questions about your exchange and will approve your class choices and make sure that you are awarded the correct number of credits when you return. The exchange office cannot advise you on any class choices or any academic issues.

You must meet the minimum average grade of your department or faculty by the point of application. Check with your academic advisor to find out what it is for you.
This academic approval is only provisional until you receive your final grades after your May exams, where if you are successful in meeting the minimum average grades required, you will receive final academic approval to go.

No. Your classes should match as much as possible what you would be taking if you stayed at Strathclyde. Some departments are more flexible allowing you to take ‘elective’ equivalents, others will need a more specific match of ‘core classes’ to work. All classes are approved by your academic advisor and failure to take the classes approved by them may result in you having to repeat the year.

Rather than classes, you need to have the right number of credits. For USA and Canada this is usually between 4 – 6 classes, in France this could be 12 classes. You want to make sure that you are doing an equivalent workload in your host university. More information on the credit load is available on the host university webpages. 

No. It is not intended to add any time to your degree and any classes and credits that you take when you are on exchange, contribute to your degree. 

It depends on your department. Some departments will give you a Pass/Fail for the classes that you take abroad and you only receive the credits to allow you to proceed to the next year or graduate. Other departments will give you a grade.
